SPECIFICATION forming part of Letters Patent No. 736,054, dated August 11, 1903; Application iiled November 23,1901. Serial No. 83,448. (No model.)

To @ZZ whom, t may concern.-

Be it known that we, OLIVER HILTON ARNO and JAMES CLARKE HAGEY, citizens of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented anew and useful Improvement in Organs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is represented as embodied in an organ, either reed or, pipe, adapted to be self-playing and also to be hand-played at will.

It consists in means whereby when automatically played individual or solo notes may be automatically selected from accompaniment or other notes and may be played upon such part of the organ as may be desired for the purpose ofproducing a solo and accompaniment eiect.

It further consistsin the specific meausemployed for obtaining this result, for combining the manual and self-playing sections of the instrument, for coupling the manuals or organs where two or more are used, and in various other features of construction and organization, which will hereinafter be fully described.

In Figures 1 to 9, inclusive, the invention is represented as applied to a reed organ having three manuals or banks of keys, known as the swell, the great,and the choir.77 Figs. 10 and 11 represent a modification of the invention, to which reference is hereinafter made.

A self-playing music-sheet similar to that described in the patent to J. W. Crooks, No. 671,691, dated April 9, 1901, or other musicsheet con taining a line of independent selecting or individualizing perforations along one edge or otherwise disposed is used for governing the automatic playing of the organ.

The tracker-board which we prefer to employ has a channel in addition to the notechannels, which we have called a selecting or governing7 channel and which is used in conjunction with the additional selecting or governing perforation of the music-sheet.

The apparatus has solo and accompaniment .3 3 of Fig. 5.

stops for each organ, a pneumatic-to-manual stop, key-coupler stops, and various other stops for controlling the playing of the reeds.

The air-pressure, or wind as it is commonly called, for operating the various mechanisms is obtained from any suitable source of supply, and is distributed to the channels, diaphragm and valve chambers, reeds, dac., to be described, by means of suitable trunks, tubes, and conduits.

We will now describe the invention in connection with the drawings, wherein- Fig. 1 is a view, principally in vertical section, of enough of the organ to show the principal parts of our invention. Fig. 2 is a view, largely in left elevation, of the mechanism at the bass end of the organ, the end of the case and the outer wall of the main wind-trunk at that end being removed. Fig. 3 is a View, mainly in front elevation, of the bass end of the organ, parts being broken out to better show the mechanism which would otherwise be concealed. Fig. 4 is a view of the organ in horizontal section upon the dotted line 4 4 of Fig. 1. Fig. 5 is a view, enlarged, in vertical section, upon the dotted line 5 5 of Fig. 6. Fig. 6 is a detail View, enlarged, of a coupler for coupling two manuals together when the organ is being manually played, the sections being upon the dotted lines 1 1, 2 2, and

Fig. 9 is a detail view, enlarged, in horizontal section to illustrate a reed draw-stop pneumatic and valve. Fig. 10 is a detail view, in vertical section, enlarged. Fig. 11 is a view, enlarged, representing the form of key primary valve which we prefer to use. Fig. 12 is a view, enlarged, principally in plan and section, to better illustrate some of the channels and passages to which reference is hereinafter made. Fig.

13 is an enlarged view of the primary diaphragm-pneu matic, with its associated parts. Figs. 14, 15, and 16 are enlarged sectional details showing the connections between certain passages by means of valves of peculiar construction, described below. Figs. 17 and 18 show details, in perspective, enlarged, of

Various passages and Valves and their relation to each other, as described below. Fig. 19 is a View, enlarged, principally in horizontal section, and it shows the location of the passages d4 d5, hereinafter referred to, with respect to the channels e e e2, without, however, indicating the connections. Fig. 2O is a View, principally in vertical section, taken through the passage d5 and channel e2 and showing the connection between said passage and said channel. Fig. 2l is a View, partly in vertical section and partly in dotted outline, showing the connection between the passage d5 and the channel e. `Fig. 22 is a View, principally in horizontal section, upon the dotted line 22 22 ot' Fig. 2l, to further illustrate this connection. Fig. 23 is a view in verticaLsection and in dotted outline to represent the connection between the passage d5 and the channel e'. Fig. 24 is a View in horizontal section upon the dotted line 24 2-1 of Fig. 23 to further illustrate this connection, Figs. 2O to 24, inclusive, showing the connections between the passage d5 and the channels e e e2. Fig. 25 is a View in vertical section, taken through the passage d4 and the channel c, representing in full lines the connection between the two.

Fig. 27 is a View in horizontal section upon the dotted line 27 27 of Fig. 26. Fig. 28 is a view in vertical section and dotted outline of the passage d4 and channel c2, showing the connection between them; and Fig. 29 is a View in horizontal section upon the dotted line 29 29 of Fig. 28, still further illustrating the connection, and Figs. 25 to 29, inclusive, showing the connections between the passage d4 and the channels e e e2. Fig. 30 is a vertical section across the reedboX of Fig. 10, enlarged, and upon the dotted line 30 30 of Fig. 10 to show the relation between the inlet-ports and outlet-port of each reed-valve.

Referring to the drawings, in Fig. 1, A represents the bank of keys called the swell,7 A the bank called the great, and A2 the bank called the choiiu The organ has, of course, the necessary stops for its actuation, including a solo or individualizing stop for each bank, an accompaniment-stop for each bank, a pneumatic-to-manual stop, the usual reed draw-stops, and coupler-stops.

B, Fig. l, is the wind-reservoir or bellows, which receives wind under pressure from any suitable source through the inlet-pipe l) and holds it under pressure for distribution to the main wind-trunks and other conduits or passages of the apparatus, which preferably open from or connect with the main wind-trunks. There are two of these trunks, one at each end of the organ. One only is shown. It is numbered 1. They connect the bellows or reservoir with the swell, great, and choir reedboxes 2, 3, and 4. (See Fig. l.) The trunks supply wind, by means of suitable connecting tubes or conduits, to the wind-chamber 5 of the music-box, the wind-passage 6 of the primary pneumatics, the Wind-passages 7, 8, and 9 of the manually-operated valves of the three manuals A, A', and A2, the wind-passage 10 of the draw-stop valves, the wind-passages l1, 12, and 13 to the reed-valve channels and controlled by the valves of the secondary pneumatics, the passage 14 (see Fig. 2) to the primaryindividualizing-valve, the passage 15 to the secondary individualizing-Valves and to one of the valves controlled by the pneumatic-to-manual stop, and to a passage (not shown) connecting the trunk with the second and third pneu matic-to-manual Valves.

C, Fig. 1, is the tracker-board partly contained in the music-chamber 5 and has the usual note-channels c and also the solo-governing channel c. (See Fig. 3.) The perforated musicsheet c2 and its holding and winding spools c3 c4 are also contained in the chamber 5, and the music-sheet is drawn by the winding-roll over the ends ofthe tracker-board channels in the usual or in any desired way.

The tracker-board has a channel for each note that is played and an additional channel which governs the playing of certain or individual notes.

Fach of the note-channels c, designed to provide a solo or give expression by introducing a quality or kind of tone Varying from that of the other notes, (the unselected and selected notes being so separated and controlled,) is connected with a primary diaphragm-pneumatic, which is lettered D. The note-governing channel c' is connected with a Valve D, Fig. 2, which controls the voperation of the individualizing-diaphragms d, Fig. l, and the accompaniment-diaphragme dl through the secondary individualizingvalves D2 and D3. (See Fig. 2.)

The primarypneumatic D is operated when a perforation in the music-sheet permits the wind-pressure in the music-box 5 to enter a channel in the tracker-board and reach it. This wind impulse serves solely to actuate the pneumatic and to cause the valve in the primary pressure-passage 6, Fig. 1, to open a port between the primary pressure-passage and the vertical channel d2, whereby windpressure from the passage 6 is admitted to the said vertical channel d2. The pressure thus supplied the vertical channel d2 continues so long as the said valve remains open, and the valve is held open by the pneumatic so long as the perforation in the music-sheet permits pressure to pass from the box 5 through a channel of the tracker-board to the pneumatic. There is a separate primary pneumatic for each note-channel.

Each ot' the channels d2 has a horizontal extension, which is lettered d3, Fig. 4 and Fig. 17, and which is only a continuation of the channel d2 and is horizontally arranged for the purposes of convenience. It is connected, when permitted, by the individualiz- IOO IlO

ing-diaphragm d, Figs. 1 and 4, or the accompaniment-diaphragm d' with either the individualizing-channel d4, Fig. 4, or the accompaniment-channel cl3, the diaphragms CZ d' being automatically controlled as to their action by the absence or presence of pressure upon them, and this is provided by means of the passages d6 and (Z7, Fig. l, which are connected by means of the valves D', D2, and D3, Fig. 2, with the source of wind-pressure through the passage 15.

By reference to Fig. 2, where the diaphragms CZ d' are shown, it will be noted that they cover perforations leading to the channels d3, d4, and cl3, respectively. Each channel d3 has two perforations, one under valve d, the other under the valve el', and the diaphragm CZ also closes the perforation leading to the individualizing-channel d4, while the diaphragm d' also closes the perforation leading to the accompaniment-channel d3. The construction of these diaphragms and their operation with relation to these perforations is similar in character to the diaphragm-valves ft2, which closes two perforations t" i3, all as described-hereinafter, and shown in Figs. 5, 6, and 14.

The valve D' is the primary individualizing-valve and controls the operation of the secondary individualizing-valves D2 and D3, and in the following Way: The expression or governing channel c of the tracker-board is connected by a passage with'the chamber of the primary pneumatic D', and when itis permitted by the music-sheet to reccive pressure from the music wind-chamber 5 it serves to operate the valve of the primary pneumatic and admit wind by the supply-passage 14, Fig. 2, to the pneumatic chambers of the secondary indiVidnaliZing-valves. These valves are operated simultaneously and are constructed so that one admits pressure to the accompaniment wind-passage d3, Figs. l and 2, or relieves it of pressure, while the other relieves the solo wind-passage el? of pressure or provides it with pressure, the wind being taken from the trunk through the passage 15 and alternately supplying the passage d6 or dT, according as the primary valve is allowed to be actuated by the individualizing perforation and channel or is held from operation by the closing of the channel. Normally the valve D2, controlling the solopassage 6X7, is open to admit pressure to hold the solo-diaphragms closed While the valve D3 is closed to relieve the accompaniment wind-passage d of pressure, whereby the accompaniment-diaphragms are free to operate in playing accompaniment-notes. While the wind makes direct connection through the port of the valve D2 to the solo wind-passage cl?, it does not make direct connection through the valve D3 with the accompaniment Wind-passage cl3, but passes from the valve D3 and through the pneumatic-to-manual valve D4 to the passage The reason for this is that when the self-playing apparatus is not used it is necessary to prevent escape of wind from the solo and accompaniment channels through the open primary valves, and this is done by maintaining pressure in both the passages d3 and C17, whereby both sets of diaphragms d CZ' are held closed. The release of pressure in the music-box 5 which then occurs will cause the primary pneumatic D', Fig. 2, to remain inactive, and thereby permit wind taken through the passage 15 to holdl open the valve D2 and admit pressure to the channel di.

The operation of the pneuinatic-to-manual stop releases the pressure which the pneumatic ,c of valve D4, Fig. 2, receivesfrom the wind-passage 10 and permits the pressure received by passage 15 to operate the pneumatic to move the valve D4 to a position which allows pressure to enter the passage d3 and cuts off the exhaust through the port beneath valve D3 and permitting pressure through the channel (Z6 to close the diaphragm d'. The pneumatic-to-manual stop also operates two other valves, one, the valve D3, Fig. 2, to prevent the escape of wind from the wind-passages controlling the secondary valves through the exhaust-tube g2, Fig. 1, to be hereinafter described, the other, the valve D3, lwhich permits connection to be made between the passages or channels of the secondary valves and the manual or key valves.

The valves D5 and D, actuated by the pneumatic-to-manual stop, are constructed like the pneumatics D2 D3 and need not further be described, the movement of the drawstop in one direction causing one pneumatic to close one valve and the other pneumatic to open the other, and the closing of the drawstop reverses their action. The valve D3 controls the pressure in the diaphragm valvechamber D7. The presence of pressure in this chamber closes the loop-passages, one of which (lettered d3) is shown in the channel e2 and beneath its controlling-diaphragm in the chamber D7, between all the exhaust extensions of the secondary channels and the exhaust-passages, thereby cutting out the automatic exhaust from the secondaries when the organ is being played manually. The release of the pressure in this diaphragm-chamber permits the normal connections with the exhaust to be resumed. The valve D6 con- IOO IIO

IZO

trols the pressure inthe diaphragm valvedividualizing and accompaniment pressure impulses and that whether such impulses shall actuate individualizing-notes or accompaniment-notes depends upon the controlling and separating diaphragms del', Figs. 1,4, and 17, which are actuated or held from actuation by the primary individualizing-valve D', Fig. 2, controlled as to its action by the individualiZing-passage of the tracker-board. We would here remark that each of the two passages d6 di is common to all the accompaniment or the individualizing controllingdiaphragms and pressure is present in or absent from either as a whole, so that all the controlling-diaphragms of each passage are either dormant under the iniiuence of the common pressure or permitted to be active because of its absence.

When accompaniment-notes are played, the individualiZing-primary is not actuated, and the normal condition of the passages cl Z7 is that of pressure in the solo-passage CF and the absence of pressure in the accompaniment-passage d6. The wind is then free to pass from the channels of the trackerboard to the primary pneumatics for the actuation of the Valves to permit air to pass from passage 6 through the channels d2, Fig. l, d3, Fig. 4, past the diaphragm d to the accompaniment-channels d5, Fig. 4, and thence, as will hereinafter be explained, to the secondary pneumatics. When an individualizing or solo note is to be played, the governingperforation of the music-sheet, which controls the playing ofthe note, permits pressure to pass through the individualizingchannel of the tracker-board to the individualizing-primary D', Fig. 2, and causes it to operate the secondary individualizing-valves D2 D3, reversing the positions of each, and thus admitting pressure to the accompaniment-passage d6, permitting the exhaust of pressure from the solo-passage C57. This closes and holds closed the diaphragms d', connecting the channels cl2 d3 with the accompaniment-passage d5, and leaves the diaphragms d free to connect said channels d2 cl3 with the solo or individualizing channels d4, (see Fig. 4,) so that a solo-note may be operated. Actuating the primary then causes Wind to enter the channels cl2 d3 and pass diaphragm-valve d into the solo-channel d4. We Would say at this point that the duration of individualizing pressure thus obtained is sufficient to actuate a secondary pneumatic, but is so quickly released that pressure taken from another source is employed for maintaining the secondary pneumatic in its oppassages e, e', and e2 are the means whereby either the wind impulse for an individualizing-note or the wind impulse for an accompaniment-note is delivered to a secondary pneumatic of either the swell, great, or choix' division of the organ.

lt should be understood that there are three separate secondary pneumatics for each notechannel of the tracker-board. These are arranged in lines, one line connecting with the reed-box valve of the swell-division, another line with the reed-box valve of the great-division, and the third line connecting With the reed-box valve of the choir-division.

Each line of secondary pneumatics is brought into action or held from action by means of draw-stops, which are hand-actuated and which permit the individualizingnotes and the accompaniment-notes to be played at the same time upon the reeds of any one of the three divisons, swell, great, and choir, or any number of them. Usually the individualizing-notes will be played upon one of the three divisions, while the accompaniment is being played upon the other two or either of them.

It should be understood that each of the channels e c' e2 is connectible with an individualizing-passage d4 and an accompaniment-passage d5, there being one group of these channels c e' e2 for each pair of passages cll d5 and for each note played. Each individualizing-passage dlis connectible with the channels e c' e2 by cross connections, which are controlled by the diaphragm-valves c3 c4 e5, (see Figs. l and 3 and also Figs. l2 to 29, inclusiva) which may be termed individualizing stop-valves.

In Fig.3 the location of the diaphragmvalve is shown only by its casing e4. It is, however, like in construction the diaphragmvalves e3 c5. These valves control, respectively, the cross connections c6 c7 es, connecting each individualizing-passage (Z4, respectively, with its group of channels e e e2, (see Figs. 25 to 29, inclusive,) and they are arranged in horizontal series. Each series of valves is normally held closed by pressure common to all the valves of the series and are caused to be operated upon the release ot this pressure by pressure in the passage d4. The valve-closing pressure is obtained by means of the valve-chambers e ew en, the valve-chamber e9 being common to all the diaphragm or stop valves e3, the Valve-chainber @lo being common to all the diaphragm or stop valves e4, and the valve-chamber e11 being common to all the diaphragm or stop Valves e5. Each of these valve-chambers e9 el e is connected with and receives pressure 'from the draw-stop-valve box l0 and is controlled by a draw-stop. The drawing of a stop serves to release the wind from the chamber which it controls and permits the valves of such chamber to be operated.

cl2, Fig. 2, is the draw-stop valve controlling the pressure in valve-chamber e9. The other draw-stop valves for the valve-chambers el() e, respectively', are not shown. They are similar in construction to the draw-stop Valve TOO IIO

@12 and serve to connect the stop-valve box 10 with the valve-chambers 610 and e11, respectively, so that the diaphragm-valves e4 and e5, common, respectively, to these chambers, are also actuated, as are the valves e3 of the chamber e9. The draw-stops are used in the customary manner of such stops in the playing of the instrument.

The accompaniment-passages are connected at will with the channels e e e2 by means of the diaphragm-valves @13 @11 e15,which are like the diaphragm-valves e3e4e5 and may be termed accompaniment stop-valves and control the cross connections e 611 613, connecting the passages d5', respectively, with the channels e e e2. (See Figs. 1 and 3 and also Figs. 19 to 24, inclusive.) The diaphragm or accompaniment stop-valves @13 e11 @15 are arranged in horizontal series like the individualizing stop-valves c3 e1 e5 and are contained in valve-chambers and held closed by pressure and are operated upon the release of pressure.

c1f is the valve-chamber common to all the valves e151, e111 is the valve-chamber common to all the valves @11, and @21 is the valve-chamber common to all the valves @15. (See Figs. 19 to2-l, inclusive.) Each of these Valve-cham bers receives windofrom the draw-stop-valve boX 10. A draw-stop valve similar to the draw-stop valve @12 of'Fig. 2 is employed for each valvechamber and controls the operation of all its stop-valves. By these cross connections and valves the solo-passage Fand the accompaniment-passage d5 are each connectible at will with either of the three channels e e e2 of each group common to a single solo and single accompaniment channel and in any order desired or simultaneously with two or all of them, according as the draw-stops controlling the actuation of the valves are drawn, it being understood that there are six draw-stops for this purpose, one for each series of diaphragm-valves c3 e4 c5 and 613 @11615, one set of draw-stops controlling the connection of all the solo-passages d1 with the three organs and the other set of draw-stops controlling the connection of all the accompaniment-passages d5 with the three organs. The location of the connection between the solo-passage d1 and the channel c. and that ot' the valve controlling the connection are represented in Fig. 25. The location ot` the connection between the solo-passage d1 and the channel e and that ot` the valve controlling the connection are represented in Figs. 26 and 27. The location of the connection between the solo-passage d1 and the channel c2 and that of the valve controlling the connection are represented in Figs. 28 and 29. The location of the connection between the accompaniment-passage d5 and the channel c and that ot the valve controlling the connection are represented in Figs. 21 and 22. The location ot the connection between the accompaniment-passage d5 and the channel e' and that of the valve controlling the connection are represented in Figs. 23 and 24. The location ofthe connection between the accompaniment-passage d5 and the channel e2 and that of the valve controlling the connection are represented in Fig. 2t).

We have now shown how the wind impulses are received by the channels d2 d3, diverted from them to the iudividualizing and accompaniment channels, and from them at will delivered to the seeondarypneumaticsof anyone or more of the three divisions of the organ. There are two other sets of valves which affect the delivery of these impulses, which we have termed automatic cut-ods. One set is located in the accompaniment-channels d5 and the other in the solo-channels d4, and each valve of each set is connected with the passage of the other, whereby it is caused to be actuated by pressure therein. The cut-off valve in the solo-channel we have lettered M, and the cut-oit valve in the accompanimentchannel is lettered M'. The channel connecting the accompaniment-channel with the valve M of the solochannel is lettered m, and the channel connecting the solo-chan nel with the accompaniment-valve M' is lettered m. These valves are not operated in lines, but individually by pressure in one or the other of the two channels. To understand the use ofthese valves, it should be borne in mind that an individualizing-perforation of the music-sheet permits what be termed an instantaneous action 1 of the solo or individualizing diaphragm-valves d, and the passing of the perforation away from the individualiZing-chan nel immediately restores the pressure to the solo-passage d? and to the individualizing diaphragm valves d and releases it from the accompaniment-passage d and its diaphragm-valves d'. Therefore the pressure permitted by the acting note-perforation of the sheet which had been individualized would then pass by the valve d' into the accompaniment-channel, and lthus actuate au accompaniment-note To prevent this action, we have employed the valve M and have caused itto be actuated by the invidualizing puit or pressure as it passes through the individualizing-channel d4,thepressuresimultaneously passing bythe passage m to the diaphragm-valve M and closing it. This closing pressure is maintained on the valve during theplaying of the individualizingnote by back pressure from the secondary pneumatic through the channel d4 to the valve M. After the note has been played the back pressure is removed, thev valve M thus released, and the accompaniment-note may then be played.

To permit ot the playing of asustained accompaniment-note, it is necessary that the solo-channel of that note should be held closed withoutinterfering with the playing of other solo-notes, and this is accomplished by closing the solo-channel d4 by means of the diaphragm-Valve M, the continued pressure in the accompaniment-channel d5 by means IOO IIO

of the channel m also serving to maintain the Valve M closed so long as the note is played. The valveMist-hen released. Without these automatic cut-olf valves the individualizing-notes would not be sharp, sustained, and well defined and the accompaniment and solo notes would notbe held separate throughout their length.

All of the secondary pneu matics have the same construction which will be described in detail hereinafter, and each comprises a pneumatic 627, Fig. 7, which actuates a valve 62S, which controls the pressure iu a passagef, extending to a reed-valve F. (See Fig. l.) The presence of wind in this passage closes the reed-Valve and holds it closed. Its absence permits the reed-valve to be blown open, permitting the wind to pass the Valve from the reed-box and actuate the reed. The actuation of the pneumatic @27 causes the valve @2S to close the portf andA to open the portf, which connects the passagef to the outer air, so that pressure in the passage fmay then escape and the reed-box valve be thus released frompressure and permitted to be operated. A by-passage f2 extends from the wind-passage 1S to the pneumatic-chamber @31 or to a passage in it. It is controlled by the pallet-valvef3 in said passage 13. The passage is closed when the pneumatic @27 is dormant. to play a note and upon the release of pressure from the passagef the pallet-valvejx3 is lifted, permitting pressure from the passage 13 to pass to the pneumatic-chamber @31, sustaining the pressure received, and thus insuring a continuance of its operation. The pressure thus delivered to the chamber also maintains the back pressure in the channel, which serves to keep closed during the playing of the note the valve M, Fig. 4. Upon the release of pressure in the pneumaticchamber the valve @28 returns to a position which connects the passagej1 with the pressure-passage 13 and which permits the palletvalve to close the by-passage f2. Th-is bypassage is employed to sustain the pressure impulse, which is delivered by the passage d2 upon the actuation of the individualizingvalve by the expression-actuating channel.

The reed-valve F upon release of pressure permits wind to iiow from the wind-supply passage f5 through a passage f6 to a reedfl, thus actuating the reed. (See Figs. l and l0.) We prefer the construction ot' reed-valve like that shown in Figs. l, l0, and 30, having a head provided with a number of holes extending from the reed-box to the Valve-chamber and surrounding the outlet-passage from the valve-chamber to the reed. (See Fig. l0, where f8 is the head, f9 represents the various inlet-ports to the chamber beneath the diaphragm or reed valve, and f is the outletpassage from beneath the diaphragm to the reed, the said passage turning at an angle in the head to permit it to extend about the reedbox.)

Upon the operation of the pneumatic vsaosa Thus far the wind-pressure for actuating the various devices has been used in the following way: lirst, wind taken from the music-box to actuate the pneumatics of the primary valves; second, wind taken from a supply-passage through channels controlled by the individualizing and accompaniment valves to actuate the pneumatics of the sec- `ondary valves; third, wind taken through passages to control the operation of the individualizing and accompaniment valves; fourth, wind taken through passages controlled by the draw-stops to valves governing the connection of the individualizing and accompaniment channels with the secondary pneumatics of any desired organ division; fifth, wind taken from a supply-conduit by passages extending to the reed-valves and controlled vby the secondary valves; sixth, Wind taken for operating the reeds.

The wind for actuating the secondary pneumatics is exhausted by passages independent of the main supply-passages. It is not feasible to exhaust through them, the main supply-channel, as they are liable to be closed by either the cut-off valves or the separatingvalves. We have therefore arranged for the independent passage of the exhaust to the channels d2 through the tubes g2. While the channel of each secondary may have its individual exhaust to the channel d2, to save and simplify connections the channels of all the secondaries controlled by a single primary valve are connected at the point where they are most closely associated with a common chamber, which chamber is connected by a single tube g2 with a channel d2. Therefore one exhaust-channel serves three secondaries, one in each line or organ. The exhaust can take place only when there is no pressure in the channel d2. To prevent pressure from the channel d2 running back through the passages to the secondaries, and thus operating the secondaries, it is necessary that each of the secondary channels extending to the exhaust-chamber G should have a check-valve g to close against the end of each of said passages, and thus not only prevent the pressure from the channel d2 from reaching the secondary in this way, but also preventing pressure from any one of the actuating secondaries from reaching others of the group.

The reeds are operated in sets by draw-r stops. (See Figs. 2 and 9.) Each draw-stop serves to control a Valve, (not shown,) a duplicate to cl2, Fig. 2, which opens or closes the passage h', Figs. 2 and i), extending from the source of wind-supply l0, Fig. 2, to the pneumatic h2, Fig. 9. The pneumatic is in the form of a small bellows having a movable side h3, from which extends an arm h, which carries a valve h5. Vhen there is pressure in the pneumatic h2, the valve h5 is closed by a spring h6, thereby closing the port 4, Figs. l, 9, and l0, which connects the trunk with the reed-box and with a set or stop of reeds.

The release of pressure in the pneumatic h2 IOO IIO

IIS

permits the pressure in the wind-trunk to operate the movable side h3 to overcome the pressure of the said closing-spring 7i against the valve h5, and thus move the valve from the port 4L to open it. The presence of pressure in the pneumatic h2 balances the pressure of the wind against it and allows the pressure in the reed-box when the valve h5 is closed, we have provided a relief-valve havingthefollowingconstruction: Avalve-chamber h? receives pressure through the by-passage (shown in dotted lilies) h8 when the valve h5 is open, and this forces the diaphragm 7i 'in said Valve-chamber against its seat and closes the outlet 1h12 and holds it closed, so that pressure may not then escape from the reed-box through the relief-passage hw to the outlet k12. Upon the closing of the valve h5 the valve-chamber 7i is relieved from pressure upon the diaphragm, and any Vpressure remaining in the reed-box passes through the relief-passageh10 under the diaphragm, which it then lifts to the outlet 7tlg. (See Fig. 9.) The diaphragm may have a small perforation 7tlg, through which the pressure behind it may be released after it has been shut oit by the valve h5.

When it is desired to cut out the self-playing mechanism of the organ and to connect the manual, the stop which we have called the pneumatic-to-mannal7 is operated, and this serves to operate the three valves which we have already described-viz., the valves D4, D5, and DG, Fig. 2. The stop also serves at the same time to release pressure from the music-box 5 in the usual way.

The key-valves of the manuals are connected with the channels of the secondary pneumatics and serve to actuate the reeds or permit of their actuation in the same manner as though they were actuated or permitted to be actuated by the primary pneumatics ot the self-playing portion of the instrument. The passages e e e2 are extended downward suflciently to receive the necessary connections and the couplings to be described.

Each key operates in the same way in all the manuals. It serves upon being moved by hand to open a valve between a passage containing pressure and a passage extending from the valve to the secondary passage of its division or organ, which is a continuation of the same passage of the self-playing section and through which it reaches its secondarv pneumatic. The valve we prefer to employ is like that represented in Fig. ll and is constructed and operates as follows: The employment of separatin g-chann els between the automatic primaries and the secondaries and the desirability of providing some means for coupling the manuals together have rendered .it expedient to operate the secondaries by additional primaries common only to the keys of the manuals and which manual primaries are connected directly with the secondaries. Each key of each manual actuates a manual primary. The form ol" manual primary which we prefer to use is that represented in enlarged detail in Fig. 1l. The manual-key of said figure is represented as having a valve O. This valve is attached to the key, preferably by a Withholding-spri ng, and it is movable with the key. lt is arranged above the outlet of an exhaust-port o, which extends from the pneumatic-chamber 0'. This chamber receives equalizing pressure through the vent 02 from a pressure-chamber o3, which is common to all the mannal-pneumatics of a single organ. This pressure-chamber o3 is connected by a port o4 and a passage of with a downward extension of one of the secondary channels e, e', or e2, according to the organ which is operated. The channel 05 also has the outlet-port 0G to the outer air. The port o is closed and opened by the valve 07, and the port 0G is opened and closed by the valve o8. Both these valves are mounted upon a valve-stem 09, which has bearings in the guides o10 and o11 and is attached to the pneumatic 012. When the port o is closed by the key-valveO, the pressure upon the pneumatic 012 is equalized, and the valve o7 then rests on its seat, closing the port between the chamber o and the passage o5. The port o9 is then open, so that there is no pressure in the passage o5. This is normally the inoperative position ot the valve. Upon the movement of a key to play a note the key-valve O opens the port o and releases the pressure over the pneumatic and permits the pressure in the chamber o3 to move it upward, and thus lift the valves o7 o8, closing the outletport of the channel 05 and. connecting the pressure chamber o3 with it, whereby pressure is permitted to reach and operate the secondary pneumatic. lVhen the key is permitted to return to its normal position at the end of the playing of the note, pressure upon the pneumatic becomes equalized, as above explained, and the outlet is then opened to permit the exhaust or release of pressure from the secondary pneumatic through the passage 0".

To arrange all the manual primaries of a single manual upon the saine line, it will be expedient to stagger the primaries, as represented.v in Fig. ll, in which case the ports 0 or of such of the valves as may be more remote will be led or extended to a position to bringthem in line with the line O of keyvalves. By this organization there is no operative connection between the manuals and theautomaticprimaries. The automaticprimaries are connected by the separating-channels with the secondaries of each of the two IOO IIO

or more organs which may be employed. The keys of each manual are connected by their independent primaries with the secondaries of each organ. This organization is advantageous in that it permits of the introduction of the separating-passages between the automatic primaries and the secondaries and in that it aiso permits of the coupling of two or more manuals together independently of the automatic mechanism.

The various divisions of the organ when hand-played are adapted to be coupled with each other, so that two or more divisions may be simultaneously played. Each coupling connecting the divisions of the organ has the same general construction, and adescription of one will answer for all. Four of these couplings are shown for making the various connections and each is controlled by a coupling-stop. Y 'Y YWe will describe the coupler-choir to great-or that connecting the passages e and c?. When the coupling-stop is operated, pressure which is contained in passage t', Fig. 5', is released. This permits pressure to pass from the secondary passage c2, Figs. 5 and 6, ofthe great-organ division -by means of a passage i', extending to one side of the flexible diaphragm 2 to a passage 3, extending to a passage i", connecting with the parallel secondary passage c' of the choir-division of the organ. The presence of pressure in the passage t' closes the diaphragm-valve i2, and the presenceof pressure in the secondary passage e', Fig. 6, of the choir-organ closes a check- Valve s (dotted) in the passages t3 and i4, so that pressure from that source may not flow backward into the passage e2, thereby reversing the coupling connection. Upon the passage c receiving wind from passage e2 in the aforesaid manner and to prevent the escape of wind through the key-valve of passage c', which as the key has not been operated is open, the loop comes in use. The loop is of ordinary construction and simply consists of two short lateral passages extending laterally from the passage e to the valve-chainber. Asi in all loops, the .main passage contains the two lateral passages of the loop, which breaks the direct continuity of the passage and causes it to be affected by means of the passages ofthe loop, thus providing a constructionl which permits of the easy employment of a controlling-valve. In this instance i9 represents thepartition in the channel e. Over and controlling this loop is placed the diaphragm-valve d, which is automatically closed and held closed by the pressure in the passage i3, Figs. 5, 6, and 18, received through the passage i7. Upon release of pressure in the passage e2 this diaphragm is free to be acted uppn and no longer serves to obstruct connection between the passage c and its controlling key-valve. This mechanism is also shown iniFig. 18.

The operation of the organ is asifollows: With the pneumatic-to-manual stopY closed, the various wind-passages controlled by the keys are disconnected and the various windpassages necessary for supplying the automatic mechanism are'connected with it, and the instrument may then be automatically played. All the notes provided by the musicsheet actuate the primary pneumatics, and as the primary pneu matics are actuated they admit wind to channels connecting them'with the secondarypneumatics. The governing-perfothe accompaniment-secondary valve, determining which'stop of reeds shall be played as solo and as accompaniment. The `wind im pulses permitted by the primary pneumatics are always very short for solo-notes and may IOO IIO

This is so When the operation of the solo-note is coincident With the operation of an accompaniment-note or a portion of it, and additional Wind is then necessary for continuing the actuation of the secondary pneumaticsfor the duration of the notes. is provided by back pressure admitted through f2 to the secondary-pneumatic channels e2 bythe opening` of the valves of the secondary pneumatics. The closing of the channels in the tracker-board by the music-sheet serves to release the secondary valves and permit them to close by the releasing of the primary valves, allowing the pressure to eX- haust directly from the secondary channels through the direct exhaust-passages g2 to the primary valves. Each primary valve has its cooperating secondary valve in each organ. In the construction shown in Figs. l and 2, as there are three organs therein shown there are three secondary valves for each single primary valve and each primary governs the direct exhaust of its three secondaries, the construction being such that the three channels of the secondary Valves are connected or merged, so that only one direct exhaustpassage g2 is needed for combining the three secondaries with their primary and also so that a com mon check-valve g serves to prevent reverse pressure or backioW through this exhaust-passage. When an accompaniment-note is operated Without a solo-note and governing-perforation interrupting it, the impulse provided bythe operation of the primary valve is coincident with the length of the note, and the secondary valve would then operate for the length of the note Without the addition of back pressure, although, as a matter of fact, back pressure is always used. The solo aud accompaniment notes being automatically separated may then be led to any organ or reed and controlled by stops as desired.
